The drill bit is an integrated drill bit, the whole drill bit has no moving parts, the structure is relatively simple, and it has high strength, high wear resistance and impact resistance. It is one of the three new drilling technologies in the world in the 1980s. Field use has proved that when drilling in soft-medium-hard formations, diamond bits have the advantages of high speed, large footage, long life, stable work, fewer downhole accidents, and good well quality.
